Cat Flea

The most common fleas to be found around your home are the cat flea, the dog flea, and the human flea.

Here we will cover the cat flea - Ctenocephalides felis.

Cat fleas can be found on cats, dogs and humans, but as the name suggests, they primarily prefer cats. The adult female lays her eggs on the host. These then fall off in your home and will eventually hatch into yet more fleas. Environmental conditions can dictate when this will occur – they can be stimulated by movement and heat, so getting rid of them. It is so vital to continue hovering after any treatment has been used. Eggs are commonly found under radiators or other heat sources.

Having a cat flea infestation is no reflection on the cleanliness of your home or, indeed, your pet, as they are so easily picked up by any animal venturing outside. Once the flea is on your cat and inside your home, they are tough to get rid of.

Pet Behaviour

Unfortunately, fleas are carriers of many diseases and have contributed to the bubonic plague pandemic in the 1300s.


In the first instance, if you suspect cat fleas, you should contact your vet, who will help you to treat your cat. You should then get professional pest controllers to deal with the inevitable infestation within your home. Fleas can lay dormant for long periods, and it can be months before you can be sure they are 100% eradicated.
